(uH)

1. Tolerance of inductance: 20% .

2. Isat is the DC current which cause the inductance drop less than 25% of its nominal inductance without current. ( 30% Typ. for SIQ73C)

3. Ir is the DC current which cause the surface temperature of the part increase less than 45oC.

4. Operating temperature: -20 C to 105 C (including self-temperature rise).
